A 300 lb. torque wrench costs mega bucks, and I can't justify 1 for a couple of times a year to check my ball and hitch bolts. But there is a much cheaper way, with a breaker bar, the proper sockets, and a 3 foot section of pipe.
Torque is measured in foot pounds. So, a 200 lb. person (like me) balanced on a point 1 foot from the bolt will give you 200 foot pounds. To get 300 lbs., I need to be 18" from the bolt.
So here is what I do. I turn the hitch sideways in the receiver. I install the proper socket on the breaker bar, and put it on the ball nut. I measure 18" on a piece of pipe, and install it as far as possible on the breaker bar. I then take my hand and center it over the 18" mark, put 1 knee on my hand, then put all of my weight on my knee....it takes a little balance, and don't have anyone taping this as it could end up on America's Funniest Videos if you lose your balance.
So what do you do if your weight isn't 200 lbs??? You divide your weight by 12 (inches), and that will give you the lbs. you exert per inch for your particular body weight. So, my 200 lbs. divided by 12 gives me 16.7. I take the 300 foot lbs. needed to torque my hitch ball, divide that by 16.7, and I see that I need centered 18" from the bolt to torque to that amount. A 150 lb. person would exert 12.5 lbs. per inch, and the center point for his weight should be 24" from the bolt for a 300 foot lb. adjustment.
I betcha this method is just about as accurate as a torque wrench.
